HOSE-COUPLING,

SPECIFICATION forming part of Letters Patent No. 426,515, dated April29, 1890.

Application filed January 10, 1890- $erial No. 336,514. (Modeh) To allwhom it may concern.-

Be it known that I, LEWIS J. RICE, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and usefulImprovement in Hose-Couplings, of whichthe following is a specification.

My invention relates to an improvement in a hose-coupling for whichLetters Patent No. 418,225 were issued to me December 31, 1889.

The objects of my present improvement are to provide certain stops whichshall operate to make the operation of coupling more convenient andcertain,to cause a circulation of water in the coupled members, andtherebyprevent the members from freezing together, and to provideimproved means for securing the coupling members to the hose, all ashereinafter fully described.

The accompanying; drawings illustrate my invention.

Figure 1 represents a side elevation of two hosesections with theircoupling members disconnected. Figs. 2 and 3 represent, respectively,end views of the male and female coupling members, Fig. 4 represents acentral longitudinal section of the hose-sections and their couplingmembers coupled. Fig. 5 represents a transverse section of the femalemember of the coupling at a, Fig. 4-. Fig. 6 represents a longitudinalsection, showing the position of the parts preparatory to securing thehose to the coupling member.

The coupling proper consists of a cylindrical male section A, having onits periphery two series of exteriorlyprojecting annular ribsh and c andan ann ularshoulder d, The

female section is provided with a hollow cylindrical portion E, which isadapted to receive the male portion A and is provided with two series ofshort interior annular ribs f and h, adapted to interlock with theribs 1) and c of the male portion. The female member is f urtherprovided with an exterior cylindrical shell I, which forms an annularchamber j, in which is a spiral spring 7c, an annular washer Thearrangement is such that when the portion A. is inserted in portion Ethe ribs 1) and c on A pass between the ends of ribs f and 72, on E,

and shoulder cl comes in contact with packing-ring m. Upon pushing Astill farther into E until ribs Z1 and 0 pass beyond the planes of ribsf and 71 spring 70 is compressed, and, the members A and E being turnedon each other until the ribs 0 come opposite the next spaces betweenribs h and opposite to ribs f, the parts are moved longitudinallyoutward by the recoil of spring 70 until ribs 1) stop against the innersurfaces of ribs f, and ribs h and e are in the same plane, thus lockingthe parts together, as fully shown and explained in my Letters PatentNo. 418,225, above mentioned. In the device there shown when the partsare forced together for uncoupling there is nothing to prevent the ribs0 from rotating beyond the point where they will pass out between theends of ribs h. For the purpose of avoidingthis difficultyI thickenevery'alternate one of the ribs 7?, so as to close the annular space abeyond them, thus forming a positive stop to the rotation of ribs 0 whenthey are exactly opposite the space between ribs h. WVhen the hose isfilled with water, chamber j becomes filled with water, which circulatesbut feebly, and hence is liable to freeze quickly.

For the purpose of causing an active circulation in chamber j, I makeseveral perfora tions 13 in the cylindrical portion A of the malecoupling in such a position that they will register with the spacebetween washerl and the outer end of E. I also contract the interiorarea of A at this point, so that the flow of water is interrupted, andprovide in E just beyond the end of A. a series of perforations r, sothat a portion of the current is diverted through perforations p,chamberj, and perforations T.

For the purpose of seeuringthe hose to the coupling each of the couplingmembers is provided with a tubular extension 3, adapted to fit theinterior of the hose, a screw-threaded flange 1 and a ring it, havingaportion of its interior surface parallel with the axis of the couplingand screw-threaded, so as to fit and screw onto flange t, and a portionof its i11- terior surface tapered outwardly and also screw-threaded, asat c.

W is a split ring having its interior sur .faee parallel with its axisaudits exterior surface tapered and screw-threaded to c0rrespend withthe tapered portion of ring a.

In securing the hose to the coupling ring a IOO is screwed onto theflange 25, as in Fig. 6,so as to expose extension 3. Extension 8 is thenthrust into the hose. Ring W is then placed in position outside of thehose and over extension s. Ring u is now screwed forward on flange t,the screw-threads of its flaring portion '0 engaging at the same timethe threads on ring W. As the ring it moves forward ring W iscontracted, and the hose is securely clamped to the coupling.

I am aware that wedge-shaped split rings secured within a sleeve havebefore been used; but, so far as I am aware, the construction has beensuch that the ring must slide longitudinally on the hose as thecompression progresses. In my device the split ring is simply compressedby the forward movement of the ring or sleeve u and is held at all timesin a fixed relation to the hose and flange t.

I claim as my invention 1. In a hose-coupling, the combination of themale section A, having on its periphery two series ofeXteriorly-projecting annular ribs 1) and c, and the female sectionhaving the hollow cylindrical portion E, adapted to receive the saidmale section, and having the interior annular ribs f and h, adapted tointerlock with ribs 1) and 0, each alternate rib h being thicker thanthe others, so as to project into the path of rotation of the ribs 0 toform stops therefor, substantially as set forth. 2. In a hose-coupling,the combination of the male section having cylindrical portion A,provided with perforations p and contracted portion on, and the femalesection having chamber j and hollow cylindrical portion E, provided withperforations 0", whereby water conveyed in the hose is caused tocirculate in chamber j, as set forth. 7

3. In a hose-coupling, the combination of the hose, the coupling memberhaving, the tubular extension 8 and screw-threaded flange t, the ring11,, having a portion of its interior surface parallel with its axis andscrew.- threaded to fit said flange, and having also the screw-threadedflaring portion 1;, and the split ring W, wedge-shaped in section andhaving its outer surface screw-threaded to fit ring a, all arranged toco-operate as and for the purpose specified.
